Tip If you want to replace both AC PEMs without shutting down the router, repeat this procedure for each
AC PEM, one at a time. Do not use this procedure if both AC PEMs have failed; instead, use the
procedure in the “Replacing Both AC PEMs” section on page 16.
Step 1 Remove the front cover by lifting it up slightly and then pulling it toward you.
Step 2 Turn off the AC PEM you are replacing by pushing down the power switch to the standby position
(Figure 5).

Caution Do not power off both AC PEMs, or the system shuts down and all data traffic stops. Power off only
the AC PEM you are replacing.
Step 3 Unplug the AC-input power cable from the power plug on the front panel of the AC PEM. For safety,
also unplug the other end of the power cable from the AC-input power source.
Tips For true redundant power protection, ensure that you are using a separate AC-input power source for
each AC PEM.
Step 4 Use the screwdriver to loosen the captive screws on the AC PEM you are removing. Then pull the PEM
from the chassis by using the handle on the faceplate (Figure 6 on page 13). Set the AC PEM aside.
